You could do a lot worse than an Alexander / Deckel, but make sure you buy one that is "tooled up".
For many years I ran an Adcock Shipley 1ES with a Bridgeport vertical head grafted onto the overarm, the problem was it was too tall to fit my garage at the time so when I got the chance of my Alexander it was a no brainer.
They are very versatile and there is not much you cannot do on one with the right attachments.
Have a look at the gear hobbing thread for some inspiration.
